The continent’s ice sheet is already a major contributor to rising seas, and increased volcanic activity could amplify the problem. Antarctic sea ice has been shrinking in recent years, hitting ...
The melting of all of the ice in West Antarctica would increase global sea-level rise to 4.3 m (14 ft 1 in). [98] Mountain ice caps that are not in contact with water are less vulnerable than the majority of the ice sheet, which is located below sea level.
Over longer timescales, the West Antarctic ice sheet, which is much smaller than the East Antarctic ice sheet and is grounded deep below sea level, is considered highly vulnerable. The melting of all of the ice in West Antarctica would increase global sea-level rise to 4.3 m (14 ft 1 in). [24]
The melting of all the ice in West Antarctica would increase the total sea level rise to 4.3 m (14 ft 1 in). [119] However, mountain ice caps not in contact with water are less vulnerable than the majority of the ice sheet, which is located below the sea level. [120] Its collapse would cause ~3.3 m (10 ft 10 in) of sea level rise. [121]
Antarctica’s vast expanse of sea ice regulates Earth’s temperature, as the white surface reflects the Sun’s heat back into the atmosphere. Record low sea-ice levels around Antarctica ...
Off the charts “crazy” heat in the North Atlantic ocean and record-smashing Antarctic sea ice lows last year are far more severe than what Earth’s supposed to get with current warming levels.
A map of West Antarctica. The total volume of the entire Antarctic ice sheet is estimated at 26.92 million km 3 (6.46 million cu mi), [2] while the WAIS contains about 2.1 million km 3 (530,000 cu mi) in ice that is above the sea level, and ~1 million km 3 (240,000 cu mi) in ice that is below it. [20]
The Antarctic sea ice cover is highly seasonal, with very little ice in the austral summer, expanding to an area roughly equal to that of Antarctica in winter.It peaks (~18 × 10^6 km 2) during September (comparable to the surface area of Pluto), which marks the end of austral winter, and retreats to a minimum (~3 × 10^6 km 2) in February.
